Study Endpoints
Primary Endpoints
Co-Primary: Percentage of Participants with Clinical Remission at Week 48
At Week 48

Clinical remission is defined as a Crohn's Disease Activity Index (CDAI) score less than (\<) 150. CDAI scores range from 0 to approximately 600. Higher score indicates higher disease activity.

Co-Primary: Percentage of Participants with Endoscopic Remission at Week 48
At Week 48

Endoscopic remission is defined as a Simple Endoscopic Score for Crohn's Disease (SES-CD) score of less than or equal to (\<=) 4 with at least a 2-point reduction from baseline and no subscore greater than (\>) 1 in any individual component. The SES-CD is based on the evaluation of 4 endoscopic components (presence/size of ulcers, proportion of mucosal surface covered by ulcers, proportion of mucosal surface affected by any lesions, and presence/type of narrowing/strictures) across 5 ileocolonic segments. SES-CD score can range from 0 to 56. Higher scores indicating more severe disease.

JNJ-78934804EXPERIMENTALParticipants will receive JNJ-78934804 induction dose, at Weeks 0, 4, and 8 followed by JNJ-78934804 maintenance dose, once every 4 weeks (q4w) starting at Week 12. All participants who meet the rescue criteria will receive JNJ-78934804 induction dose at Weeks 16, 20, and 24 followed by JNJ-78934804 maintenance dose q4w starting at Week 28. Participants who complete double-blind treatment phase (Week 48) and who may benefit from continued study intervention in the opinion of the investigator will have the opportunity to enter the long-term extension (LTE) phase.
